It's better than nothing, but if there is a way to get these running in numerical order, that would be preferable.

This is more or less typical 2's complement behavior.
Since the BCR basically can't "think in negative values", I can't see a way to get rid of the jump.

You don't get any negative responses at the high end of these ranges?
So does this parameter simply not HAVE negative values?
Any luck with "00 00 - 7F 7F"?

I can't test them completely -- that would take weeks -- but I tested a few at random, and they worked.  Assuming I double-checked all the numbers correctly, they should all be fine.  As soon as the above parameters have been sorted out, I can share the RM50 definitions.

Great work!
I'll think about an extension to the ini file format that will allow hierarchical groups in one file, but that's for the future...

Mark.
